T/F The Humane Methods of Livestock Slaughter Act of 1978 requires that livestock be rendered
insensible to pain before being shackled, hoisted, thrown, cast, or cut. - ANSWER ✔✔-True
T/F Antemortem inspection includes the observation of body condition of livestock to help avoid
including unhealthy animals in the human food chain. - ANSWER ✔✔-True
T/F A two stage expression operation is characterized by first reducing the size of the particle to increase
the surface area through which the expressed product may leave the raw product. - ANSWER ✔✔-true
T/F Probiotics are non-digestible food ingredients that improve the growth or metabolism of prebiotic
bacteria in the hosts intestinal tract. - ANSWER ✔✔-False, digestible
T/F During batch fermentation the growth of the culture is limited to the amount of substrate available. -
ANSWER ✔✔-True
T/F When conducting solvent extraction on a food product the density of the solvent should be as close
as possible to the density of water to achieve optimum separation efficiency. - ANSWER ✔✔-False
T/F Enzymes speed up the rate of a reaction by lowering the activation energy, but are not consumed in
the reaction. - ANSWER ✔✔-True
T/F When manufacturing a sausage product like a hot dog, an emulsion mill may be used to produce a
fine textured batter with little particle identification. - ANSWER ✔✔-True

T/F In a food system, enzymes catalyze reactions by raising the reactions activation energy. - ANSWER
✔✔-False, lower
T/F A properly performed mixing of powdered components with different bulk densities will ensure the
mixture will not separate during subsequent storage and transportation steps. - ANSWER ✔✔-True
T/F Continuous mixing devices limit the flexibility of a process system, but may increase the efficiency
thereby helping to recover the extra capital cost of the mixer. - ANSWER ✔✔-True
T/F Stoke's equation represents the velocity with which a sphere under the influence of gravity will
move through a continuous phase (liquid). - ANSWER ✔✔-True
T/F When mixing dilatant products such as Chocolate or cornflower solutions, one must run the mixing
devices at a high rate to ensure the complete mixing of the product. - ANSWER ✔✔-True
T/F The Federal Meat Inspection Act mandates the Food Safety and Inspection Service to examine and
inspect methods of livestock handling and slaughter. - ANSWER ✔✔-True
T/F Centrifugal clarifiers take advantage of the higher density of the continuous phase in comparison to
the dispersed particles being collected at the outer limits of the bowl. - ANSWER ✔✔-True
T/F Continuous membrane filtration systems are very expensive due to the need for many membrane
modules, arranged in sections that are serviced by separate pumps. These pumps are needed to
compensate for the loss in pressure resulting from loss in volume on the retentate side of the system. -
ANSWER ✔✔-True
T/F . When concentrating a compound using solvent extraction it is critical not to dry the sample to
absolute dryness - ANSWER ✔✔-False
T/F The driving force for membrane fractionation processes is the pressure applied to the permeate side
of the system. - ANSWER ✔✔-False, all pressure

take place in a single facility or in several locations depending on the consumer target. - ANSWER ✔✔-
True
T/F Over-mixing of a sausage batter can result in a tough texture and poor color due to excessive
extraction of protein from the meat tissues. - ANSWER ✔✔-True
